AUTOMATIC MUSIC-LEAF-TURNING DEVICE.

Application filed August 26, 192-1. Serial Nb. 485,494.

T 0 all whom, it may concern:

Be it known that I, ALBANO -VALERI, a citizen of the United'States ofAmeriea, residing in the city of Detroit, county of lVayne, State of Michigan, have invented certain new and useful Improvements in an Automatic Music-Leaf-Turning Device, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of these specifications.

The object of my invention is to provide a music page turning device whereby the sheets, or pages of'the music being played, may be turned over as desired by the musician without the use of the hands, or interfering with the execution of the music.

Another object is to provide a music turning device that can be operated by the foot of the musician, turning the pages automatically as desired.

A still further object, is to provide a page turning device that is simple in its construction, easily and efficiently operated, and can be manufactured at a low cost. These several objects are secured in the preferred form by the construction and arrangements of parts more fully hereinafter described.

The page turning device herein shown and described is connected with an ordinary music stand, operating in connection there with. However the page turning device may be. installed on any suitable support as on a piano or organ, and may serve other purposes.

Fig. 1, is a perspective view of the music turning device showing the general construction and arrangement of parts with the means for operating same.

Fig. 2, is a topview of the music holder showing a book in place, and the relative position of the working parts as it operates to Fig. 3, shows a detail of the operating mechanism for moving the page turning arm and the automatic page lifter, and means for connecting to the foot pedal.

Fig. t, shows the edge of one of the music pages carrying a thin strip of metallic sheet aflixed thereto, to be attracted by the page lifting magnet.

I will now describe more fully the detailed construction of the device, and the working parts thereof, referring to the accompanying drawings and the marks thereon.

' The foot pedal -1 is hinged at the base of the device in a convenient position for the operator, and is connected to the operating rod 2 by a hinge joint at the end. The operating rod -2- carries, connected thereto, an operating rack 3- which engages the pinion l, rotating same, as the foot pedal is moved up and down. Pinion 4:-- is rigidly connected to the gear sector 5- and rotates concentric therewith, while the gear sector '-5 engages the horizontal toothed rack -6, causing the same to move backward and forward as the foot pedal is moved by the operator. Connected to rack -6 is the movable page turning bar 7 which is supported at the ends by grooves in the frame, and operates below the book supporting bars, said turning bar is provided with a turning bail -8' attached thereto so as to pass over the pages of the book as the operating bar 7 moves back and forth by the movement of the foot pedal and operating mechanism. The bail -8- is so attached to the turning bar 7 that it passes outside the book supporting bar 10 and slides thereon as it moves forward without contact with the page of the book. When the foot pedal is pushed down the turning bar 7 moves forward, sliding in grooves 11, to the right of the book, carrying the bail 8- until it clears the page to be turned. During this movement, the ends of the bar 7- engages the latches 12', which are pivoted on the side of the supporting frame, and forces said latches down by means of the inclined surfaces thereon, and at the completionof the stroke, the latches -12 are raised automatically by means of springs -13 attached thereto. These latches are attached to the adjustable lifting arms 15, by means of links +14:. The said arms 15-' being connected at their free ends by an adjustable grooved cross-bar 16-, which is provided with a movable magnet 17-: with convenient means for fastening same and properly adjusting same to the edge of the page. The poles of said magnet point toward the page to be turned. On the edge of the page which is to be turned, is a thin metallic clip -18 aflixed thereto. having magnetic properties, and positioned directly under the magnet. hen the bar 7 is moved forthickness of the book.

' a toothed rack attache" t.

ward, the magnet is lowered by means of latches 12 and connecting frame -15, as soon as the bail 8 has cleared the edge of the page. As the magnet 17 touches the metallic edge 18 on the page, it at tracts same thereto, and on raising to its normal position, lifts the page under which the bail 8 inserts itself, and on the re turn motion, caused by the opposite pressure on the foot pedal 1, the turning bail 8 draws the page back in its turned position. The arms 15 may be adjusted on the pivots 19 by means of a slotted bearing to take up the variations in the 20-, of the turning bar -7 which slide in grooves 11-, are made of flexible steel springs inserted in the ends of bar -7, in such a manner that on the return stroke of the bar, they engage the ends of. the latches 12, and bend backward suflicientlyto slide by said latches.

The turning device may be made of any size, or design to suit the purpose for which it may be used. 1

I do not Wish to be confined to the exact construction of the turning device as herein set forth, but claim any page turning device that is substantially a duplication of parts and mechanism herein described.

Having fully described my page turning device, what I claim as my invention and desire to secure Letters Patent is:

1. An automatic leaf turning device of the character described compris ng a supporting frame, means forholding a book there-' on, a magnetic leaf lifting device, automatic means for operating the leaf lifter, a sliding leaf turning arm installed in the supporting frame, a toothed rack attached to the said leaf turner for operating same in combination with the leaf lifter, an operat ing gear engaging the teeth of said rack, and mean for operating and controlling the device. V v r 2. An automatic leaf turning device of the character described comprising a supporting frame, means forholdin'g a book thereon, a leaf lifting frame attached to the supporting frame, a permanent magnet mounted on said leaf lifter, a metallic leaf plate susceptible to-magnetic attraction for attach-j ment to the edges of the leaves, means for operating said leaf lifter, a sliding leaf turning arm mounted in the supporting frame for engaging and. turning the leaves, said sliding leaf The end bearings turning arm for changing the position of the bail over the book, a large operating gear mounted on the supporting frame and engaging the teeth of said rack, a pinion drive gear attached to said operating gear, a foot pedal and means for operating the gears therewith.

3. An automatic leaf turning device of the character described comprising a supporting frame, means for holding a book thereon, a magnetic leaf lifting device attached to the said supporting frame, metallic leaf plates susceptible to magnetic attraction for attachment to each of the leaves, means for adjusting the magnet frame to the leaf plates, automatic means for operating the leaf lifter, a sliding leaf turning bar mounted in the supporting frame, a leaf bail attached to said sliding leaf bar for engaging the leaf of the book after the magnetic leaf lifter has raised it clear from the book and means for operating the leaf turning device.

4;. ,An automatic leaf turning device substantially as set forth comprising a supporting frame, means for holding a book thereon, a magnetic leaf lifting frame mounted on the said supporting frame and extending over the pages of the book, a side operating cam attached to the side of the lifting frame for operating the leaf lifter, springs attached to the side of said lifter frame for holding same open, metallic leaf plates susceptible to magnetic attraction for attachment to each of the leaves, means for adjusting the leaf lifter magnet to the leaf plate,

a sliding leaf bar mounted in the support frame, a bail attached thereto for engaging the leaf after it is lifted by the magnetic leaf lifter, stubs on the ends of said ALBANO VALERI.
